Stone Chip Simulators

Stone Chip Simulators

通过 IABG 石击模拟装置能够以可再现的限定方式在部件上产生石击损伤。喷丸材料的种类和数量以及碰撞速度的可变范围较为广泛。确保所选喷丸材料的每一颗粒均具有相同的限定速度,不受其形状、大小和重量的影响。

IABG 自主开发的两款模拟装置主要适用于测试车桥弹簧、稳定杆、减震器、车桥附件、机动车或轨道车车头、车身件、燃油箱、变速箱壳体、油底壳、挡风玻璃及轮对轴。我们的模拟装置也适用于在风力转子顶端或光电模块上模拟散粒冲击。

Advantages of the IABG Grit Impact Simulator

  • The velocity of the individual particles in the discharge material is independent of weight, size and shape
  • Therefore the test is consistent and accurately reproducible
  • The method is equivalent to the standards DIN 20567 and SAE J400
  • High Variation of the area to be targeted
  • Test specimens can be rotated throughout the procedure producing a regular damage pattern
  • Large selection of discharge material (gravel, chippings, stone shards, sand or balls of various materials)
  • Simple operation without the need for extensive training
  • Reliable and low maintenance

Verification of the reproducibility of standards DIN 20567 and SAE J400

To confirm the reproducibility in accordance with the required norms, comparative tests were carried out using the different procedures and documented. With the help of imaging techniques, the damage patterns were analysed, measured and compared using statistical evaluation. With this the correlation between the two methods can be demonstrated.
